Synthesis, spectral, and thermal properties of some phosphorus-containing 9,10-anthraquininoid, thermally stable dyes

The multi-component, one-step reaction of dialkyl acetylenedicarboxylates with 1-amino-9,10-anthraquinone in the presence of triphenyl phosphite or trialkyl phosphites, produces 9,10-anthraquinone derivatives containing dialkyl(aryl) phosphoryl groups as novel, thermally stable dyes in fairly good yields. The structural characterization and some physical properties of these dyes are reported.
